It took me five minutes to solve the first part and about half an hour of ruminating to feel confident that I had the solution to the second part. No I didn’t cheat by searching for others’ solutions.
And I won’t spoil it for you by giving my answers here. Maybe later.
What’s most interesting is:
I employed a few “tactics” to break it down from what was initially a confusing mass. That certainly comes with experience.
There was a push-and-pull, a kind of tag-team effort, between intuition and drilling down (right brain and left). My intuition confirms that the answer I eventually found is correct, because it is beautiful.
Let us know what you find.
